New insights into Zebra mussel attachment fibers offer potential solutions to combat invasive species, develop sustainable materials

Science Daily - 09/12/2023
A recent study has revealed that an unlikely event, occurring over 12 million years ago played an important role in shaping one of Canada's most damaging invasive species. Zebra and quagga mussels, belonging to the Dreissenid family, are widespread freshwater invasive species throughout North America that present a significant danger to native ecosystems by competing for resources. Using a fibrous anchor called a byssus, Dreissenid mussels contribute to biofouling on surfaces and obstruct intake structures in power stations and water treatment plants.
